EXHAUST SYSTEM
6. Load the swim platform if equipped.
7. Measure the exhaust elbow waterline height.
IMPORTANT: View all boat seating as rows that are parallel to the transom of the boat.
8. Load a person weight into a seat, and measure the exhaust elbow waterline height after each
person weight is loaded onto the boat. Repeat until a person weight is is loaded into each seat
in that row.
9. Continue the process moving forward toward the bow of the boat to the next row of seats until
a person weight is loaded into each seat.
NOTE: The total weight loaded onto the boat must not exceed the maximum capacity displayed
on the capacity plate.
NOTE: The following example is provided as a reference.

EXAMPLE

NOTE: This example uses a boat that is less than 8.84 m (29 ft.) long, not including a boat that
is 8.84 m (29 ft.) long that does not have a maximum rated swim platform weight capacity, and
must add 181.45 Kg (400 lb.) to the swim platform
NOTE: Use 0.50 lb. as the break point to round up or down to obtain a whole pound.
1. Maximum load (persons and gear) from capacity plate – swim platform load = remaining weight
to be placed in the boat.
•
2. Remaining weight to be placed in the boat ÷ MerCruiser person weight = number of persons
to load onto the boat
•
3. Total number of persons – number of whole persons = remaining persons
•
4. Remainder persons ÷ MerCruiser person weight = remainder MerCruiser person weight
•
IMPORTANT: View all boat seating as rows that are parallel to the transom of the boat.
5. Using the totals in this example, load four 165‑lb. persons and one 40‑lb. person onto boat
seating with 400 lb. on the swim platform.
• 400 lb. + 165 lb. = 565 lb.
• 565 lb. + 165 lb. = 730 lb.
• 730 lb. + 165 lb. = 895 lb.
• 895 lb. + 165 lb. = 1060 lb.
Page 6 / 12
1100 lb. – 400 lb. = 700 lb.
700 lb. ÷ 165 lb. = 4.24 persons
4.24 persons – 4 persons = 0.24 remaining persons
0.24 × 165 lb. = 40 lb.
